Maybe someone here has already built some to these. I am going to salvage some cages I have around here that I am not using to make some breeder cages. I plan making them 2 X 10 feet, with 9 individual pens that are 13" wide X 20" deep. I want these to have sloped floors for egg roll out. Would a 2 inch slope for 20 inches be suitable ? or is that too much ? If I have enough wire I may make this a doubledecker to save space and have catch trays under top level.
